Final answer:
The frontal or ventral surface refers to the front side of the body. Supination is the movement that turns the palm forward.
Step-by-step explanation:
The frontal or ventral surface refers to the front side of the body. When pronation occurs, the palm faces backward, while supination turns the palm forward.
Flexion is the movement that decreases the angle between two body parts, while extension increases the angle. Hyperextension refers to excessive extension beyond the normal range of motion.
Therefore, the correct answer is B. Supination.
